Actually, the HEV suit does have a helmet, just...Gordon never seems to wear it. I guess it either folds out of the neck or he really doesn't have the one that goes with his suit, which, is actually quite obvious in-game considering Gordon can quite easily drown HEV suit or no.
I'll give it a pass on the protective value, seeing as it -is- designed for hazardous work, and while that may not be primarily in regard to bullets, flying bits of metal aren't an unreasonable hazard to experience either.
I learned:
The greatest warriors of the Xen Borderlands use only the mightiest of weapons: Guns that launch bees. (Yeah, really, the Grunts are supposed to be their main footsoldier and they use bee-cannons, which while capable of killing you aren't all that effective... No wonder they got their asses kicked.)
